T 0 all whom 2'25 may concern;-

Be it known that I, Ronnnr MIX, a

citizen of the United States, residing at Cohocton, in the county ofSteuben, State of New York, have invented a new and useful Harrow-Shoe;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to harrows and has for its object to provide aharrow shoe, which harrow shoe may be easily and quickly adjusted andsecured to the under face of a drag, said shoe being adapted to engagethe ground as the harrow drag moves over the same, thereby preventingthe wearing out of the drag bar. Also to so secure and construct theshoe that the same may be easily andquickly adjusted longitudinally onthe drag as said shoe becomes worn.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafterset forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings 2- Figure 1 is a bottom plan view of a conventional formof harrow showing the drag shoes applied thereto. i

Fig. 2 is a detail perspective view of the shoe and its adjacent parts,showing the same in positions to be assembled.

Fig. 3 is a sectional view through the for- V ward end of the shoe,showing the means for adj ustably securing the same to thedrag frame. I

Referring to the drawings, the numerall V designates a conventional formof harrow, which comprises the drag frames 2, said drag frames 2 beingformed with outwardly and rearwardly extending bars .3, which barsterminate in longitudinal bars 4. in parallel relation to each other.Where the bars 3 merge into the bars 4, a shoulder 5 is formed. In theharrows now in use the wear upon the drag frames 2 issubstantially atthe points 5, this for the reason that the bars 3 extend.

slightly upwardly, therefore the shoulders 5 contact with the ground andbecome worn. Each of the drag frames is made from'angle iron and has anupwardly extending flange 6 also a horizontaljfiange 7. Secured-to theflange 7 of the bar 8 is a wear'plate 8, which wear platemay be rivetedor otherwise secured as at 9 to said bar.

An adjustable shoe 10 is securely clamped of which the shoe 10 may besecurely clamped to the bar 4-,. The forward end of FIE.

One end of the shoe 10' is preferably wider than the width of theframe. of the. drags, however, 1ts marginal edges being provided with aseries of apertures 13, through which apertures bolts 14 and 15 areadapted to pass, said bolts in turn passing through apertures 16 ofbrackets 17 which brackets are adapted to engage the upper and innerfaces of the flanges 6. and 7.

Through constant use of, the harrowthe plates 8 and 10, become worn asat a. However, as the wear reduces the ends to a sharp edge, theadjustable plate 10 is moved forwardly so as to overlapthe end of theplate 8, this being accomplished by moving the bracket 17 and itssecuring bolts into engagement with apertures 13 near the rear of theadjustable shoe, and then looseningup on the bolt 12 and adjusting thewear plate to any desired position, after which the clamping means areagain secured.

It will be seen that a shoe forming a wear plate 1s provided which maybe cheaply constructed andone wherein the wearing out of drag frameswill be prevented.
